Broken Sensor, Transmission Rebuild
A sensor broke on this transmission. The computer is a solid state, so it had to be completely replaced. When the sensor broke it caused damage which clogged the filter. The filter didn’t allow enough fluid to pass through, and the transmission got hot. The clutch-plates and friction rings inside the transmission were bent or warped due to the heat. You can see the sensor on the back of the computer. It’s a little circle. The bent rings can be seen in the images as well.
